It would not be a patch update with out some Paladin “changes“.
Seal of Vengeance and Seal of Corruption: These seals have been redesigned to deal substantially more damage. Now, once a paladin has 5 copies of the debuff from these seals on his or her target, on each swing the paladin will deal 33% weapon damage as Holy, with critical strikes dealing double damage. In addition, the damage-over-time effect is now considered a melee attack instead of a spell attack and the effects from these seals can only be triggered by auto-attacks and Hammer of the Righteous.
With the change currently, it will take me 17.5 second to ramp up 5 stacks. To me that is a long time to get the full benefit of the spell. With all the trash, some phases with bosses and some bosses entirely SoV is pointless to use. I guess I have to seal swap SoR over SoV with some fight but that does not make it any better.
I hope there are more changes to compensate for this nerf.

More like 12 seconds, once you factor all the haste from gear and/or aura you should be ~3.0 seconds per swing:
Stack 1: 0 seconds
Stack 2: 3 seconds
Stack 3: 6 seconds
Stack 4: 9 seconds
Stack 5: 12 seconds
…which is still way too long to ramp up to “full damage output”. Weapon-switching macro to switch to fast one-hander to build stack, then switch back FTW? Maybe…
they are wanting to push you down the Seal of Casino (Command) for trash and Seal of Corruption for Bosses. If it works out this way I guess only time will tell
SoR with 5/5 SotP is far better than SoC(asinos)
Also if I have to weapon switch, then it is a design flaw
